Ran an overpowered 19-6 once. About 42 mph she started porpoising real bad. Any faster than that became weird, unpredictable, and unpleasant.

IMO, forget the factory rating of a 300 HP OB for that little boat. A 200 would be a ball of fire...a 300 overkill from a weight/danger standpoint.

Anything over 50 mph...she could chine walk over to port and be on the six 'o clock news.... :(

The Deck plate does say 300, an Evenrude G2 300 (558lbs) or even a Yammy 300(562lbs) would not add much weight over my '02 Yammy 250hp OX66(527lbs). I was thinking a 300 because that is the max HP on the deck plate and the weights for the 200's - 300's are the same, the price increase for the difference in power between those is pretty small considering the total investment.

But I would love to learn more about boats and hulls with regards to the statement, "Anything over 50 mph...she could chine walk over to port and be on the six 'o clock news....". What happens at the magical threshold of 50 miles an hour that makes the boat want to chine walk to port? With my 250, my boat will hit 47 and I have not noticed any chine walk yet, maybe once I hit that magical 50 I guess all hell is going to break loose?

This one SB shows has a 200. If had to guess max HP 225, certainly no more than 250.

It would be uninsurable with a 300, not to mention liability if involved in an accident. Just a head's up.

Nice ride

Please help he have a better understanding of underwriting guide lines for P&C business and how my boat would be uninsurable with a 300.

Scrapper, Scotty no doubt said that assuming the max HP rating was 250.  Of course she will be insurable knowing that the max rating is 300...

[gran398]

Yes that it true, an incorrect assumption on my part. My apologies.

She COULD chine walk to port as stated with excessive horsepower. Although rated for 300 HP...why would you need it? None of these boats were lofted for high speed. Designed to run good with economy in varying conditions.

But its your boat....this is just my opinion, and I'm not a naval architect. However, I have owned and run a lot of boats over the course of 50 years. Rig her up and see what you got.

Keep in mind these hulls are not designed for speed.  I get your point on the similar weights...  but that much power will not help a overloaded boat.

[scrapper01]

After a little research into the same year Wellcraft Costal 220 which I believe is understood to be the same hull, I found documentation that the boats dry weight with the I/O option to be 3800lbs, my Aquasport lists a dry weight of 3000 lbs with a 150hp motor on it. So after this discovery, what I used to fear as overweighting the boat in the past I think is fully within the boats capabilities.

I think you are all correct, the boat does not need a 300 hp motor, but for 10% more money I can get 20% more HP at the same weight, hell why not?
